Quad Port Auto MDI/MDIX 10/100Base-T Transformer Isolation ModulesFeatures• Designed for Broadcom BCM5226/5228, Level One LXT9784/9785 and Kendin KS8995/8995E chipsets• Low profile (5.8mm) and light weight (4.5 g) 10/100Base-TQuad Port isolation transformer modules designed for AutoMDI/MDIX applications• Modules meet requirements of IEEE 802.3u and ANSI X3.263• SMD packages facilitate pick and place compatability andspeed of placement while providing consistant and reliablecoplanarity• Manufactured in an ISO-9001:2000, TS-16949:2002and ISO-14001:2004 certified Talema facility• Fully RoHS compliant and meets lead free reflowlevel J-STD-020CElectrical Specifications @ 25°CInductance: 350μH minimum @ 100kHz, 100mV, 8mALeakage Inductance: 0.4μH @ 1MHzMinimum isolation voltage: 1500 VrmsOperating Temperature Range: -40°C to +85°CStorage Temperature: -40°C to +125°CStandard packing: Tape and reelQuality and consistency is guaranteed through 100% testing of the specified parameters for primary inductance, leakageinductance, turns ratio, DC resistance and interwinding capacitance.This ensures that the return loss and pulse wave shaperequirements can be fully maintained. Additionally, all parts are tested for 1500V minimum isolation.ApplicationsTalema 10/100BaseT Quad transformer modules contain transmit and receive isolation transformers to maintain consistantwave shape and suppression of common mode noise while providing equipment isolation per IEEE 802.3. High impedancecommon mode quad chokes for additional EMI suppression have been added on some models as required for FCC andCISPR 22 Class B certification.TEXQ Series -Quad Port MDI/MDIX 10/100Base-TIsolation Transformer ModulesPart NumberTurns Ratio±2%TxRxInsertionLoss(dB Typ)0.1 - 100 MHz0.5-30MHzReturn Loss(dB Min)40MHz50MHz60-80MHz1MHzCrosstalk(dB Typ)30MHz60MHz100MHzDifferential toCommon ModeRejection(dB Typ)TEXQ-400M-J1 : 1 1 : 1 -1.0 -18-14.6 -13.1 -10-65-50-40-35-40-36MTEXQ-400N-JTEXQ-400N1-JTEXQ-405N-J1-60MHz60-200MHzSchematic1ct: 1ct1ct: 1ct-1.0 -18-14.6 -13.1 -10-55-45-40-33-36-24N1ct: 1ct1ct: 1ct-1.0 -18-14.6 -13.1 -10-55-45-40-33-36-24N1.89ct:1ct1ct:1ct-1.0 -18-16-14-12-32-32-32-32-40-40N0.638(16.20)0.575(14.60)TALEMA INWK/YRPart Number19 x 0.050(19 x 1,27)SuggestedPad Layout0.030(0,77)0.076(1.93)19 x 0.05(1,27)1.102(28.00)0° - 8°0.661 0.480(16,80) (12,20)0.091(2,30)0.236(6.00)0.189(4.80) 0.020 x 0.012(0.50 x 0.30)0.950(24,13)Surface coplanarity will be
